United States Patent 3,568,260 REGISTRATION BOARD Maxwell B. Roberts, 60 W. 57th St., New York, N.Y. 10024 Filed May 7, 1969, Ser. No. 828,416 Int. Cl. A44b 21/00 US. Cl. 24-67.5 2 Claims ABSTRACT OF THE DISCLOSURE A simple durable, practical and inexpensive registration board to be used in registering colored woodcuts, the device being particularly adapted for extra large work, and there is no risk of maladjusted registrations.

The present invention relates to the registration of colored woodcuts and more particularly to a new and improved method and means for the positive attainment of greater accuracy of registration in the handling of larger woodcuts than is possible with known devices, this being a main objective of the invention.

Another object of the invention is the provision of a registration board on which a series of aligned finger actuated spring clamps are the means for releasably holding in securely clamped position the work sheet (woodcut) on which a number of complementary imprints are to be made, each by a respective inked block slidably positioned in a recessed surface of the board.

A further object of the invention is to employ the paper holding spring clamps as guides in locating registration marks on the paper for the woodcut.

A further object of the invention is the provision of clamping means for the work sheet which permits adjustment of the sheet to its original registered set-up following each of the succession of imprints made thereon.

And a still further object of the invention is to provide a registration board for use in registering colored woodcuts, which is of simple, practical and inexpensive construction, easy to operate and which is particularly adaptable in registering with almost perfect accuracy woodcuts up to and beyond 18" x 24".

To these and other ends, as will become apparent from perusal of the following detailed description, the invention consists of certain parts and combination of parts as set forth in the accompanying drawing forming a part of the specification. It is to be understood, however, that the drawing is for the purpose of illustration only, and that such changes and alterations may be made as do not depart from the spirit of the invention as set forth in the specification and particularly defined in the appended claims.

The drawing is as follows:

FIG. 1 is a top plan view of the registration board;

FIG. 2 is an edge view of the board as seen from the bottom of FIG. 1; and

FIG. 3 is an enlarged sectional detail on line 33 of FIG. 1, looking in the direction of the arrows;

FIG. 4 is a side view of the invention as seen looking in the direction of the arrows 4-4 of FIG. 1; and

FIG. 5 is a sectional detail on line 5-5 of FIG. 1 looking in the direction of the arrows.

In the drawing, like reference numerals indicate similar parts throughout the several views.

Numeral 6 represents a rectangular base made preferably of plywood and having a finished top surface 7 on which iinked printing blocks, not shown, are supported. Secured to this top surface 7 by screws 8, in this instance, are wood strips 9 and 10 the outer edges of which are flush ice with top and one side edge, respectively, of the base 6. The surface 7 is thus recessed with respect to the bordering strips 9 and 10* and provides a rectangular working area open along the bottom and one side edge of the base 6 for manipulation, as will be explained, of the work sheet or, in other words, the woodcut on which colored impressions are to be printed and the printing blocks to be used in this operation.

Longitudinally spaced along the side border strip 9, and secured thereto are a plurality, three in this instance, of finger actuated paper clamps of well known construction and use, each clamp being indicated as a whole by numeral 11. It will be observed that the clamps 11 have three exposed sides and that each clip includes a split cylindrical clamping member 12. And, it may be stated that on the average, these members 12 are approximately 2%" long.

As above stated the instant invention is particularly adapted for use in registering colored woodcuts. In operation the following method is employed;

The edge of the paper, otherwise referred to as th work sheet, is inserted under the member 12 of each clamp 11. The paper is then marked along the three exposed sides of the clamps, as indicated at 13, FIG. 1 for each clamp, and thus providing nine registration marks along the border of the paper or three equally spaced groups of three marks each. The paper is then turned back upon itself along the inner edge of the border strip 9 and after which the first inked block is moved into the recessed upper left squared corner formed at the intersection of the inner edges of the top and side strips 10 and 9, respectively. The paper is then unfolded, spread over the contacting inked surface of the block and the ink worked into the paper. If the paper moves during the inking process (as is usually the case in this and other methods) there results no risk of maladjusted registrations, for before the second inked block is placed in the squared recess, the paper is again positioned as indicated by the original registration marks. Thus, the artist can continue with any number of blocks and each one will be exactly positioned 'by the nine registration marks on the paper.

It may be stated that, with the clamps 11 positioned as shown, the width of the border along the side edge of the paper may be increased by the addition of one or more strips, not shown, to the inner side face of the strip 9.

What I claim is:

1. The method of registering colored woodcuts on a registration board which includes releasably clamping the paper to be printed along a side edge to a fixed supporting member, scribing registration marks on the paper, folding the paper back upon itself along the said marks to permit the placement of an inked block on said board, unfolding the paper to receive on its under face an imprint from said block, and then successively repeating the operation, each time using a different block, but after first adjusting the paper to bring all said registering marks to their initial position of registration.

2. The method of colored woodcut registration according to claim 1 but characterized by the said clamping means determining the location and character of said registration markings.
